Field of the Invention The present invention relates to an apparatus for cleaning an end face of a metal frame of a centrifugal casting apparatus for pipes. 2. Description of the Related Art As a method of manufacturing cast iron pipes and ductile cast iron pipes, there is known a centrifugal casting method in which a pipe is formed by a centrifugal force from molten cast iron supplied in a metal frame rotated around an axis at a high speed. ing. In this centrifugal casting method, a core is mounted concentrically on the receiving side of a metal frame in order to shape the inner surface of the receiving port of the tube. This core is automatically removed from the metal frame together with the cast iron tube if the cast iron tube is pulled out after the tube casting.However, since the core is formed by solidifying molding sand with a coagulant, The coagulating material is decomposed by the heat of the time, and the molding sand collapsed by the decomposition may fall and accumulate on the inner surface of the opening end of the receiving portion of the metal frame. If such sedimentary sand is left unattended, the core will be set in the above-mentioned socket at the time of the next casting. After removing, before installing the core in the metal frame,
The casting sand accumulated on the opening end of the metal frame was removed by a brush by a regular manual operation of an operator. [0005] However, such an operation is a dangerous operation because it is performed in the vicinity of a high-temperature metal frame.
In addition, since a brush having a long handle is used, there is a problem that it is difficult to perform the operation. Further, a brush device is provided in the vicinity of a bogie on which a metal frame is mounted, and once the bogie is stopped, the brush device is protruded toward the rotating metal frame by automatic control to automatically remove the collapsed sedimentary sand. However, there is a problem in that the cycle frame of casting is restricted, for example, the carriage of the metal frame must be stopped until the cleaning by the brush device is completed. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has been made to solve the problem of automatically cleaning collapsed sand deposited on the opening end of a receiving opening of a metal frame without restricting the cycle time of casting. is there. [0008] In order to solve the above-mentioned problems, an apparatus for cleaning the end face of a metal frame of a tube casting apparatus according to the first aspect of the present invention is provided on a receiving mold side portion of a metal frame of a centrifugal force casting apparatus for pipes. A brush is attached to the end of the metal frame on the receiving mold side, and the brush is moved to the receiving mold of the metal frame from a working position in which the brush can contact the end of the metal frame on the receiving molding side. It is supported so as to be able to reciprocate up to a lying posture that does not interfere with the core setter to which the child is fitted. Therefore, after the cast tube is pulled out from the receiving-molding side of the metal frame, the metal frame end surface cleaning device, which had been in the lying position, was raised to the working position, and the rotation of the metal frame was performed. After cleaning the opening end of the metal frame and setting the core in the lying position again by the next time the core is set by the core setter, without stopping the bogie, casting, pulling out the casting tube, until the next core setting by the core setter The end face of the metal frame can be smoothly cleaned without any restriction on the series of casting steps. Next, an embodiment of the present invention will be described.

It has been like that. [0012] The metal frame end face cleaning device 10 uses the cart 1
An upper portion of the metal frame 2 in the vicinity of the receiving mold side 2a;
The core 8 is provided at a side position that does not interfere with the movement of the core setter 9 that automatically sets the core 8 on the receiving mold side 2a. As shown in FIGS. 2 and 3, an actuator 11 is provided on the carriage 1 for reciprocating rotational movement. The actuator 11 is connected to the actuator 11 via a parallel link 12, a support member 14, and a brush arm 20. A brush 13 for cleaning an opening end face of the receiving side 2a of the frame 2 is attached. The parallel link 12 is connected to the actuator 1
A drive arm 15 connecting the first member 1 and the support member 14, a sub-link having one end connected to the carriage 1 and the other end connected to the support member 14 so as to be parallel to the drive arm 15 and keeping the posture of the support member 14 constant. When the rotary arm 15 is rotated by the actuator 11, the brush 13 comes into contact with the end 2a of the receiving frame 2 of the metal frame 2 as shown by the phantom line. The core 2 can be reciprocated up to a lying posture which does not interfere with the core setter 9 for setting the core 8 in 2a. The auxiliary link 17 has two male screw rods 17a, 17a arranged in the axial direction, and a long nut 17b inserted between the male screw rods 17a, 17a.
By rotating the long nut 17b around the axis, the entire length of the sub-link 17 can be adjusted. The support member 14 is provided with a support shaft 19 on the bearing portion 14a so as to be substantially parallel to the drive arm.
The brush arm 20 is attached to the support shaft 19 by the mounting block 2.
1 and attached to the support member 14 through the drive arm 1
5 is attached so as to be able to adjust the rotation posture. The mounting portion 21a for receiving the brush arm 20 of the mounting block portion 21 is a brush arm 2

Therefore, the operation of the core setter 9 does not interfere with the brush 13 and is performed smoothly. Then, after setting the core, the carriage 1 is advanced toward the molten metal supply device, and when it is turned back again, the molten metal is supplied into the metal frame, and the cast iron tube is centrifugally formed. After the formation of the cast iron tube, the cast iron tube is pulled out of the metal frame by a drawing device (not shown). After the cast iron tube is pulled out of the metal frame, the actuator 11 is driven, and the action of the link 12 causes the operation of the link 12 as shown in FIG.
The brush 13 is erected so as to assume the working posture as shown in FIG. At this time, the metal frame is being slowly rotated. Accordingly, the end of the metal mold 2 on the side of the receiving mold is the core 8
Before setting, the brush 13 is automatically cleaned by the rotation of the metal frame. When cleaning is completed, the actuator 1
1 is actuated in the reverse direction, and the brush 13 falls down to the side of the metal frame 2 as shown in FIG. Therefore, the core setting process by the core setter does not become any obstacle, and the end face of the metal frame can be cleaned without limiting each process. As described above, according to the apparatus for cleaning the end face of a metal frame of a tube centrifugal casting machine of the present invention, after the cast iron pipe is pulled out of the metal frame, the core is set by the core setter.
